Filter by:Due to many vascular branches on the supra-hepatic vena cava (SHVC) and infra-hepatic vena cava (IHVC), in the whole procedures of preparation of liver donation, preparation of hepatic vena cava (HVC) is the most key and troublesome step. Magnetic Spiderman (MS) is a novel surgical instrument, designed and created to solve the vital problems of preparation of liver donation's HVC. Therefore, the aim of this study is to evaluate the feasibility and security of MS when using it prepare the liver donation's HVC.
The study aims to study the impact on different surgical approaches for lumbar active discopathy. This inflammatory disease of the disc and adjacent vertebral endplates can induce low back pain with inflammatory-like features. Lumbar fusion is proposed to the patient when conservative management is not enough. This fusion can be obtained by an anterior muscle sparring approach or by a posterior muscle decaying approach. The goal with this single center retrospective study is to identify the surgical approach that offers to the patient the better long term functional outcome. A phone call would allow us to ask patients a few questions: - Mcnab's criteria - Roland Morris Disability Questionnaire The patients medical file review would also allow us to identify: - the length of hospital stay for the discectomy (in days) - incidence of Failed Back Surgery Syndrome - incidence of redo surgeries - incidence of adjacent level diseases - incidence of dural tears and eventual complications (meningitis, orthostatic headaches,...) - incidence of iliac vessels injuries and eventual complications (thrombosis, need for revascularisation,...)
Ventilation management in paediatric anaesthesia remains difficult because of the wide range of age and weight, and therefore practices are heterogeneous. In adults, protective ventilation during anesthesia is now a standard of care but in children there is no level of evidence to recommend it. The aim of the study was to describe current practice and the factors associated with the use of high tidal volume during anaesthesia in children in France.
Acute myocardial infarction (MI) is a significant complication following non-cardiac surgery. We sought to evaluate incidence of perioperative MI, its preoperative - and intraoperative - risk factors and outcomes after this complication.
To investigate pre-op peripheral nerve block in reducing peri-op IL-6 level and post-op pain
Protective ventilation decreased morbidity and mortality in adults' patients and is now a standard of care in intensive care unit and in anesthesiology. In children, there is no evidence in the literature to recommend protective ventilation during anaesthesia. Moreover the ratio of instrumental dead space to tidal volume is higher in children than in adults. Therefore, it is difficult to propose an "optimal" tidal volume for all children. The objective of this study is to evaluate the use of alveolar ventilation (estimated by the volumetric capnography) in children under anesthesia. The hypothesis is that in children, alveolar ventilation reported to ideal body weight is a constant to maintain normocarbia, unlike the tidal volume.
Cardiovascular autonomic neuropathy in diabetic patients, hypertension, sympathovagal imbalance, orthostatic hypotension, painless myocardial infarction, ischemia, left ventricular dysfunction, cardiac sympathetic and parasympathetic innervation disturbances, qt interval prolongation and sudden deaths observed. The purpose of this study is to evaluate the relationship between cardiovascular autonomic neuropathy and perfusion index in spinal anesthesia
Acute myocardial infarction (AMI) is a significant complication following non-cardiac surgery. The investigators sought to evaluate incidence of perioperative AMI, its preoperative and intraoperative risk factors and the outcomes after this complication.
The term acute kidney injury (AKI) is used to describe a rapid deterioration (hours to days) of renal function. This rapid deterioration leads to accumulation of plasma waste products, such as urea and creatinine. Accumulation of urea and other nitrogen-containing substances in the blood stream lead to a number of symptoms, such as fatigue, loss of appetite, headache, nausea and vomiting. Marked increases in the potassium level can lead to irregularities in the heartbeat, which can be severe and life-threatening. Fluid balance is frequently affected, though blood pressure can be high, low or normal. Pain in the flanks may be encountered in some conditions (such as thrombosis of the renal blood vessels or inflammation of the kidney); this is the result of stretching of the fibrous tissue capsule surrounding the kidney. Perioperative AKI is a leading cause of morbidity and mortality; It is associated with increased risk of sepsis, anemia, coagulopathy, and mechanical ventilation. The first publication of consensus criteria for AKI was published in 2004. The system was named RIFLE (risk, injury, failure, loss of kidney function and end-stage renal failure) and used sCr or urine output to define AKI. Later, in 2007, a modified definition of the RIFLE criteria was published by the Acute Kidney Injury Network (AKIN) .Although the AKIN criteria evolved from the RIFLE criteria, a major advance was the understanding that even small changes in sCr concentrations are associated with increased morbidity and mortality. The AKIN criteria allowed definition of AKI even without knowledge of baseline sCr. In 2012, a clinical practice guideline of AKI was proposed by the Kidney Disease Improving Global Outcomes (KDIGO) Foundation. The guideline included a comprehensive review of AKI definition, risk assessment, diagnosis, prevention, treatment and renal replacement therapy. A common practice to maintain effective blood volume and thus kidney perfusion is intravenous (I.V.) hydration. Correcting hypovolemia is an essential perioperative hemodynamic goal and appropriate hydration is considered important for the avoidance of AKI. Perioperative fluid therapy has been studied extensively, but the optimal strategy remains controversial and uncertain. Much of the current debate surrounds the type of fluids administered (colloid versus crystalloid), the total volume administered (restrictive versus liberal), and whether the administration of fluids should be guided by hemodynamic goals (goal directed [GD] versus not goal directed). Administering a large amount of I.V. fluid in the perioperative period is a common clinical practice. Although fluid loading may expand intravascular space, improve organ perfusion or tissue oxygenation and reduce minor postoperative complications in laparoscopic surgery, excessive fluid may also increase some perioperative complications. Intraoperative urine output is often monitored but rarely responds to fluid administration. Clearance of fluid during general anesthesia is only a small fraction of that observed in conscious volunteers. Infusion of crystalloids during anesthesia shows reduced clearance and slower distribution such that intraoperative oliguria may not reflect fluid status or predict future AKI. Given that liberal fluid administration can be correlated with worse postoperative outcome, the recommendation to maintain urine output of at least 0.5 ml/kg/h should be considered.
During the induction period of general anesthesia, surgical patients are inevitably experienced a short period of apnea for endotracheal intubation or other airway manipulation. In order to minimize the risks of hypoxemia during the establishment of artificial airway, pure oxygen (FiO2=100%) is commonly applied to the patients throughout the preoxygenation and induction period. However, high concentration of oxygen therapy has been shown to result in hyperoxemia and substantial oxygen exposure during perioperative period or critical care. There is currently no clinical evidence indicating that preoxygenation with a lower oxygen partial pressure (such as FiO2=60%) during the induction of anesthesia increases the incidence of hypoxemia or other complications. The findings of this proposed clinical study may provide fundamental evidence for the use of different oxygen concentrations in clinical anesthesia during the induction period, and determine the effects of inspired oxygen concentrations on the general postoperative outcomes during general anesthesia.
